A George Strait concert at an outdoor stadium (Nissan Stadium) in Nashville, Tennessee was cancelled by a forced evacuation — due to approaching thunderstorms — just before 10 PM local time on 29 July 2023<\/strong><\/a> (0300 UTC on 30 July). GOES-16 (GOES-East)<\/em> \u201cClean\u201d Infrared Window (10.3 \u00b5m<\/strong><\/a>) images (above)<\/strong><\/em> showed (1) the dissipation and departure of an initial cluster of thunderstorms near Nashville (those storms caused a delay in the start of the concert, with a shelter-in-place warning being issued by stadium officials just before 5 PM local time or 2200 UTC<\/strong><\/a> — which was then lifted about 45 minutes later, allowing the concert to begin at its originally-scheduled time), and (2) the development of a new cluster of thunderstorms in north-central Tennessee shortly after 9 PM local time or 0200 UTC<\/strong><\/a>, which then approached the Nashville area. The coldest cloud-top infrared brightness temperatures were around -70\u00baC (brighter white pixels embedded within darker black regions).<\/p>\n

GOES-16 Infrared images that included an overlay of\u00a0GLM<\/strong><\/a>\u00a0Flash Extent Density<\/strong><\/a>\u00a0and contours of\u00a0Lightning Cast<\/strong><\/a> Probability (below)<\/strong><\/em> revealed an appreciable amount of lightning activity with these 2 clusters of thunderstorms (which was the primary concern for both the initial shelter-in-place warning prior to the concert start time, and the second shelter-in-place warning that led to the concert cancellation). There was a tight gradient in the contours of LightningCast Probability along the leading edge of the second cluster of thunderstorms as it approached Nashville.\u00a0 \u00a0<\/p>\n

KBNA is located about 5.5 miles southeast of Nissan Stadium.<\/p>\n
